The July/August 1987 issue of ST-Log magazine has an article by Matthew Stern called "Atari Sets Off Fireworks!" It features an interview with Robert Veline of Astro Pryrotechnics, a California-based fireworks company. In 2017 I read the article and contacted Robert. I interviewed him for ANTIC: The Atari 8-Bit Podcast. (The interview will be published July 4, 2017.)
After the interview, Robert sent me pictures of his Atari 800XL-based fireworks rig; and the floppy disks with the custom software, which I digitized.
This archive.org item includes:
- a scan of the original article in ST-Log magazine
- Robert's pictures of the fireworks rig
- a ZIP file containing ATR files of the disks Robert sent me, including the source code for the fireworks system
